Transanal minimally invasive (TAMIS) mucosal resection with muscular plication for patients with obstructed defecation syndrome-A prospective pilot study.

What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
backgroundRectocele and intussusception are frequently observed during defecography as potential contributors to obstructed defecation syndrome (ODS). We aimed to describe our initial experience with transanal minimally invasive surgery (TAMIS) mucosectomy with muscular plication, as a novel surgical approach to treat patients with ODS.
methodsConducted between August 2021 and October 2023 at the Medical University of Vienna, 11 patients (8 female) were prospectively enrolled and underwent TAMIS mucosectomy with circular mucosectomy and longitudinal muscular plication (internal Delorme's procedure). Functional outcome and quality of life were assessed by using standardized questionnaires pre- and postoperatively. The median follow up time was 16 months.
resultsIn defecography rectal intussusception could be observed in all patients and rectocele was found in nine patients (81.8%). The median age at the time of surgical procedure was 56 years (range 28-76 years). Neither intraoperative nor postoperative complications occurred. The median ODS score decreased from 16 to 11 points (p = 0.171), and four out of five patients (80%) with preexistent fecal incontinence reported improvement of their symptoms postoperatively (80%), though one patient had new onset of fecal incontinence symptoms. No significant changes could be demonstrated in terms of quality life by using the Short-Form Health Survey 12 (SF-12) survey.
conclusionsOur initial results showed that TAMIS mucosectomy is a safe technique, offering a viable alternative transanal approach for treating symptomatic ODS. Future studies with a larger sample size and a longer follow-up period should enhance the robustness of our preliminary findings.
